[0039] Please refer to Figure 1 and Figure 2 A vehicle-mounted GPS installation structure in a preferred embodiment of the present invention includes an installation box 100, a flexible pad 200, a GPS body 300, a limiting member 400 and an elastic member 500.

[0040] The installation box 100 is provided with an installation cavity 110 with a front opening, and the left and right side walls and the top wall of the installation cavity 110 are provided with elastic pre-tightening pieces 120. Figure 6 As shown, specifically, a window 121 is provided on the side wall of the installation cavity 110, and an elastic pre-tightening piece 120 is provided in the window 121. One side of the elastic pre-tightening piece 120 is connected to a side wall of the window 121, and the other three sides are spaced apart from the window 121. The middle part of the elastic pre-tightening piece 120 is arched toward the installation cavity 110. The flexible pad 200 is attached to the top wall, bottom wall, left wall and right wall of the installation cavity 110. The GPS body 300 is inserted into the installation cavity 110, and the outer wall surface of the GPS body 300 is attached to the flexible pad 200 and clamped by the elastic pre-tightening piece 120. The GPS body 300 is provided with a limiting hole 310. The limiting member 400 has a limiting state of being embedded in the limiting hole 310 and a disassembly state of being detached from the limiting hole 310. The limiting member 400 is movably installed on the installation box 100 to realize the switching between the limiting state and the disassembly state. The elastic member 500 is used to apply an elastic force to the limiting member 400, and the elastic force is used to push the limiting member 400 in the disassembled state to move toward the limited state, so that the limiting member 400 can be stable in the limited state when no external force is applied, thereby achieving stable limiting of the GPS body 300.

[0041] The utility model provides a vehicle-mounted GPS installation structure, which utilizes a flexible pad 200 and an elastic pre-tightening piece 120 to elastically pre-tighten and flexibly support the GPS body 300, thereby eliminating the installation gap between the GPS body 300 and the installation box 100, so that the GPS body 300 is stable after installation. In addition, the buffering of the elastic pre-tightening piece 120 and the flexible pad 200 can effectively reduce the collision with the side wall of the installation cavity 110 and reduce vibration noise; the cooperation of the limiting member 400 and the elastic member 500 can realize the limitation of the GPS body 300, and when disassembling, only the movable limiting member 400 is needed to complete the disassembly of the GPS body 300, and the disassembly is simple.

[0042] Reference Figure 2 In some embodiments of the present invention, a convex strip 320 is provided on the upper side of the front end of the GPS body 300, and a limiting hole 310 is provided on the convex strip 320; a mounting bar 130 located above the convex strip 320 is provided on the front end of the mounting box 100, and a limiting member 400 is elastically and movably installed on the mounting bar 130 and aligned with the limiting hole 310. Both the convex strip 320 and the mounting bar 130 are provided at the front end position to facilitate the operation of the limiting member 400.

[0043] Reference Figure 3 In a further embodiment of the present invention, the mounting bar 130 is provided with a guide hole 131 aligned with the limiting hole 310. The limiting member 400 includes, from top to bottom, a guide post 410, a protruding ring 420, and a plug post 430. The guide post 410 is movably inserted into the guide hole 131, and the plug post 430 is used to insert into the limiting hole 310. The protruding ring 420 has a larger profile than the guide post 410. The elastic member 500 is a compression spring sleeved on the guide post 410. The ends of the compression spring respectively abut against the mounting bar 130 and the protruding ring 420, achieving movable guidance through the guide hole 131 and the guide post 410. The abutment between the compression spring and the protruding ring 420 exerts an elastic effect on the limiting member 400, thereby pushing the plug post 430 into the limiting hole 310. The bottom edge of the plug post 430 is chamfered to facilitate insertion, and the diameter of the plug post 430 matches that of the limiting hole 310.

[0044] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, the lower end of the mounting bar 130 is provided with an embedded groove 132 for embedding the compression spring, and the embedded groove 132 is aligned with the guide hole 131; the upper end of the convex ring 420 is provided with a sinking groove 421 for embedding the lower end of the compression spring, so that there is enough space to accommodate the compression spring.

[0045] Reference Figure 3 and Figure 4In a further embodiment of the present invention, a threaded column 411 is provided at the upper end of the guide column 410, and the outline of the threaded column 411 is smaller than that of the guide column 410; a nut 412 is threadedly connected to the threaded column 411, and the outline of the nut 412 is larger than the guide hole 131, that is, the outer peripheral outline of the nut 412 is larger than the diameter of the guide hole 131, so that the nut 412 cannot pass through the guide hole 131, thereby preventing the guide column 410 from detaching from the guide hole 131 when disassembled.

[0046] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, the guide holes 131, the limiting holes 310, the limiting members 400, and the elastic members 500 are arranged in multiple groups along the left-right direction. Specifically, the guide holes 131, the limiting holes 310, the limiting members 400, and the elastic members 500 are arranged in three groups along the left-right direction; thereby achieving multi-position limiting and making the limiting more stable.

[0047] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, a serial rod 600 is further included. The serial rod 600 is provided with a sleeve hole 610. The sleeve hole 610 corresponds to the threaded column 411 one by one, so that the serial rod 600 is sleeved on all the threaded columns 411. The nut 412 is located above the serial rod 600 to limit the serial rod 600, so that the serial rod 600 connects all the limiting parts 400 in series. During operation, all the limiting parts 400 can be lifted as a whole and switched to the disassembly state to facilitate the disassembly operation.

[0048] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, the tandem rod 600 is provided with a lifting handle 620 to facilitate lifting the tandem rod 600 .

[0049] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, the flexible pad 200 is made of sponge or rubber material, so as to have a better flexible supporting effect.

[0050] like Figure 5 As shown, the GPS body 300 can be connected to the power supply of the vehicle body to achieve long-term power supply. A socket 140 is provided on the rear wall of the installation cavity 110, and an interface adapted to the socket 140 is provided on the rear side of the GPS body 300 to achieve docking with the socket 140. The rear side of the installation box 100 is connected to the power supply of the vehicle body through a connecting harness, thereby transmitting power to the GPS body 300, so that the GPS body 300 does not need to replace the battery regularly.

[0051] Of course, in other embodiments, the GPS body 300 may also have a built-in battery, and the battery only needs to be replaced regularly.

[0052] like Figure 7 The present invention also provides a road-rail dual-use vehicle, comprising an on-board GPS mounting structure and a vehicle body 700. The vehicle body 700 is provided with road wheels 710 and rail wheels 720 at its bottom. The rail wheels 720 can be raised and lowered to switch positions to accommodate different driving conditions. The mounting box 100 can be secured to the vehicle body 700 using fasteners.
